| Short Description |
The Department of Ecology measured sediment accumulation rates in four inlets of south Puget Sound between September 2007 and June 2008. The four inlets were Case, Carr, Eld, and Budd. Sedimentation rates measured in Eld and Budd inlet were three to five times higher than rates measured in Case and Carr Inlets. (Also see abstract below) | |||

| Abstract | Long Description |
The Washington State Department of Ecology used sediment traps to determine gross sediment deposition rates in four inlets of South Puget Sound between September 2007 and June 2008. One station was located in each of the following inlets: Case, Carr, Eld, and Budd. The data collected will be used to verify sedimentation rates simulated in a water quality model for dissolved oxygen in South Puget Sound. Mass accumulation rates ranged from 0.2 to 2.1 g/cm2/yr. Based on means, accumulation rates measured in Budd and Eld Inlets were approximately three to five times higher than those measured in Case and Carr Inlets. Mass accumulation rates for Eld and Budd Inlets were similar to those measured in other urban embayments of Puget Sound. Total organic carbon (TOC) flux rates ranged from 0.005 to 0.063 gOC/cm2/yr. The highest TOC flux rates for TOC were measured in Eld and Budd Inlets. TOC flux rates were much lower in Case and Carr Inlets. |
